.ROBERT `nnnKEjoE NEWARK, `NEW JERSEY.

Letters .Patent No. 99,542, dated February 8, 1870.

'lo all whom it may concern Beit known that I, ROBERT DRAKE, of Newark, in the county of Essex, and Stat-e of New Jersey, have invented a newr and useful Improvement in Gas-Burn ing Sad-Irons; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable othersI skilled in the art to make and use the same, reference being had to the accompanying drawing, forming a part'of' this specification.

This invention relates to new and useful improvements in sad-irons, which are heated by the combustion of gas therein, and consists in the peculiar mode of introducing Vthe gas into the interior, and in the formation of the interior ofthe bottom or face of the sad-iron, and in'the devices in combination therewith for insuring 'a perfect flow and combustion ofthe gas, as will be hereinafter more fully described.

In the accompanying drawing- Figure 1 represents a. vertical longitudinal section,

lthrough the line :t :c of fig. 2. l

Figure 2 is a vertical cross-section, through the line y y of Iig. 1.

Figure 3 is a section of fig.I 4, through the line z z. Figure 4 is a side yiew of a device for holding the flexible tube, used for conducting the gas to the sadiron, in proper position.

Similar letters of reference indicate corresponding parts.

I obtained Letters Patent of the United' States for a gas sad-irou on the 6th day of J une, 18,65, but I have found that by the arrangement described therein, `I cannot produce a perfect combustion ofthe gas,

as no adequate provision is made for a sufficient supply of air, the gas being discharged and ignited in a single jet.

In my 'present improvement I introduce the gas through a number of small orices or perforations in a tube, A, which passes through the back end of the iron, and screws on toa piu' which is fast in the front end or toeof the iron, as seen in the drawing at A'.

The bottom of the-interior or combustion-chamber of the sad-iron is curved transversely, as seen in fig. 2, andthe gas-jets impiuge against Vthe upward-inclining sides C G, and meet a. full supplyof oxygen,

which passes into' the chamber opposite the jets, as seen in the drawing at d.

e represents airlorices, through the rear end of the iron, for increasing the supplyof oxygen. By this arrangement, a reverberatory action ofthe dame is produced, and a perfect combustion is obtained. frepresents air-apertures directly beneath the cover Grof theiron. v

The escape of heated air through the chimney or tube H, serves to produce a draught of air through the chamber, and thus insure a full supply for the perfect combustion of the gas. i

lhe perforatedtube A- is couuectedwith the dexible-tube B, which is attached to the gas-supply pipe or ordinary gas-burner. i Y

To prevent this iexible tube B from breaking or becoming collapsed, andA thereby interfering with the How of gas through the tube, I apply a stay, I, made of wire, bent so asV to form two eyes, through which eyes the tube is passed, as seen in fig. t.V This preserves and maintains a proper curve in thel tube, and prevents it from breakingor collapsing by its own weight,'a`nd obstructing the ow of the gas.

4'Ihe'general construction of the sad-iron having been described iu my present patent, and forming no part of my present claim, audbeing also shown inY my present drawing, any further description is deemed unnecessary.

Having thus described my invention, I

What I claim as new, and desire to secure by Letvters Patent. is I The combination, in a gas-burning sad-lron, of ther perforated tubeA, fastened in the comlmstion-chamber, as shown, the airorifices d, e, and f, and the inclined surfaces C C, arranged substantially as and for the purposes herein described.

The above specification of my invention signed by me, this 16th day of June, 1869;
